Filed: 1965-09-02
Abstract: 1,065,438. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 2, 1965 [Sept. 29, 1964], No. 37466/65. Addition to 930,476. Heading B6F. Record controlled or electrical signal controlled input arrangements; error checking arrangements. - A typewriter is operated by an encoding device as described in parent Specification 930,476 and the encoding device is provided with error indicating means which disables the encoding device when one of the slides of the encoding device fails to operate in aligned relationship. Encoding device comprises a set of metal code slides 30 each operated by a respective solenoid 4-9 in response to a signal received from a perforated tape, magnetic tape or computer output data channel to displace the code slides 30 against the bias of springs 34. Displacement of slides aligns openings 31 permitting one of cam controlled stop pins to penetrate the aligned one of openings 31 and enter the underlying openings 41 of encoding slides 40 which are moved laterally under control of cam 47 to superpose their lugs 48 over the punches 2. To prevent erroneous punching when any of the slides 30 or 40 are not displaced, the encoding slides are provided with check openings 42 which overlie error indicating openings 52 in an error indicating slide. When all associated openings in slides 30, 40, 50 are aligned a sensing pin 22, associated with stop pin 21 through a pin arm 20, passes through the opening 52 preventing the slide 50 to move under bias of spring 54 and open contact 58 connected in the circuit of main drive motor 18 of the punch mechanism for punches 2. On the other hand when one of the slides 30 or 40 fails to move, none of the openings 42 will be aligned thereby preventing the respective sensing pin 22 from entering the underlying opening 52 and the slide 50 when released for movement by cam 57 and bell-crank 55 will be displaced to open the contact 58 and arrest the motor 18.

Title: Improvements in self-regulating reciprocating action pumps, and in particular in fuel injection pumps, for internal combustion engines
IPC: F02M59/36
Filed: 1957-12-10
Abstract: 835,344. Fuel injection pumps. BESSIERE, P. E. Dec. 10, 1957 [Dec. 13, 1956], No. 38394/57. Class 102(1). In a reciprocating pump a by-pass conduit is open by a valve member at the commencement of the discharge stroke, the valve being braked in its movement to close this by-pass conduit. A valve 12 is moved by liquid supplied under pressure through conduit 4, passage 17, groove 18 in the pump piston 1, past non-return valve 17a to chamber 13a, against the action of a spring 16 to open the by-pass conduit 11 when the piston 1 is in its lower dead centre position, this liquid also fills the pumping chamber 5 through conduit 3. As the piston 1 moves on its discharge stroke it first closes conduit 17 then conduit 3 and through groove 24 opens the interruption in a relief conduit 23, liquid in the chamber 13a is then free to flow past throttle 20, through conduits 10 and 23 to drain thus allowing the valve 12 to move downwards. When the portion 12a of the valve is about to close the by-pass conduit 11 the chamber 13a is connected to conduit 21 via a passage 22 in the valve portion 12b thus allowing a sudden closing of the by-pass 11 at which time liquid in the chamber 5 passes to the delivery line 7. Since the time of closing of the by-pass 11 is constant for a setting of the throttle 20, as the speed of the piston 2 increases more liquid will be by-passed on each stroke of the piston. In order to ensure a full movement of the valve 12 by the liquid pressure a throttle 25 is inserted in the feed conduit 3 to the pumping chamber. Delivery is ended when a passage 9 in the piston by-passes the liquid through conduit 10. The throttle 25 may be replaced by a passage in the plunger which allows communication between the feed conduit 3 and the pumping chamber 5 before the piston 1 reaches its lower dead centre position, and closes this communication before opening the conduit 17. A separate pump may be used to supply liquid to move the valve 12 and this pump may also feed the liquid to the chamber 5. In this case the second pump is 180 degrees out of phase with the first pump.

Abstract: 868,418. Variable pitch propellers. UNITED AIRCRAFT CORPORATION. Dec. 16, 1957 [Dec. 18, 1956], No. 39013/57. Class 114. An hydraulic control system of a variable pitch propeller comprises a feathering valve 32 and a control valve 34 which control the distribution of a fluid to a hydraulic motor to vary the pitch of the propellers in a manner similar to that described in Specification 824,078. The present invention also includes provision for adjusting the supply for reversing the propellers. The feathering valve is normally adjusted through a lever system 124 by a cam 118 provided with three peripheral sections 126, 128, 130 of differing radial dimensions. With the section 128 engaging the member 132, the feathering valve 32 is in its so called " closed position " for routine pitch adjustment by the valve 34, and with the section 130 engaging the member 132 the feathering valve is lowered by the lever 140 moving to the right and rising on the roller 142 thus causing lever 144 to rotate in an anticlockwise direction. Both these operations being similar to that described in the abovementioned Specification. For propeller reversing the section 126 of the cam engages the member 132 and the lever 140 is moved to the left causing the roller on the end of the lever 144 to drop on to the portion 154 of lever 140. The lever 144 thus rotates in a clockwise direction and raises the feathering valve 32 whereby the fluid supply flows through conduits 28, 28a, 26a and 26 to the control mechanism and the pitch is reversed. The hydraulic supply is provided by a main pump 62 and a standby pump 64 as described in Specification 868,419. Specifications 683,906 and 724,284 also are referred to.
